The IC-820 is the perfect choice for using in all of the larger rooms/spaces in your home. From the kitchen to the living room to the master bedroom, the IC-820 is a speaker that you'll spend hours and hours listening to. The injection-molded polypropylene cone gives detailed bass response and the 1" pivoting silk tweeter can be aimed at your favorite listening spot. The integrated one-piece baffle / woofer basket adds enhanced rigidity and complements the deep bass sound. The IC-820 is acoustically matched to the IC-620 and the IW-620 so you can mix and match between the sizes as needed. Use the IC-620 in smaller rooms and the IC-820 in larger rooms or rooms with higher ceilings. The IC-820 uses the patented SwiftLock by Swarm tool-less installation system which lets the speaker be installed quickly and easily with the simple press of a button at each of the three mounting dogs.
